2) The concept of descent with modification, or evolution, has a great deal of evidence in its support. Indicate the major types of evidence.
Some of the major types of evidence that supports evolution are from the similarities that organisms living on distant locations have to one another. Charles Darwin logic when he summarized his findings of five year collecting evidence around the world while he was on the HMS Beagle. Darwin noticed the similarities between animals and plants on the same continent though they were diverse.
On a molecular level protein structures and gene sequences is used to determine the evolutionary relationship with the random mutations in our genes. Our genes contain instruction to create protein which creates out physical traits. It is those traits that are molded by natural selection. It determines how well the individual organism can live in changing environments and the chance to have as many offspring as possible.

Australopithecus afarensis who existed 3.5 million years ago and a 4.4 million year old skeleton of an Ardipithecus ramidus are the closest science has come to discovering the human lineage. Shattered Ancestry an article written by Katherine Harmon discusses the remains of two hominids found within Ethiopia. These skeletal remains have created a huge controversy within the topic of evolution questioning many assumptions that have been made referencing the human lineage. The skeleton of the Australopithecus afarensis was named Lucy and was discovered in 1974. The evidence of her walking upright on her two feet essentially guaranteed her a spot in the human lineage line. Lucy was a chimplike ape that was said to walk upright making scientists believe the human ancestry was simple. The complete skeleton found in Ethiopia of an Ardipithecus ramidus named Ardi completely changed all assumptions made from scientists about the complexity of the human lineage. These remains have encouraged researches that the human line is not the only lineage to have evolved but the chimpanzee line has undergone drastic changes as well. There are many traits that researchers have always directly linked to the human lineage however since these discoveries occurred researchers are reconsidering. The recent discoveries that have shattered what has always suggested what linked a species to the human lineage have changed the certainty of whether it is possible to confidently identify the human’s last common ancestor. Majority of scientist had forgotten that there would have been many hominid species living together at one time. New theories have been suggested since scientists revealed that the foot of a hominid found called the Burtele site was found ju...
Many discoveries have been made that give more and more clues to the history of life on earth. Paleontologists find artifacts throughout the world that not only answer many questions but also raise many new ones. A topic that is still a mystery today is the origin of man. Scientists often debate over where man originated from and who some of his prehistoric relatives were. Some people think that all men are related, and that there has been inter breeding between different groups of men. (I.e. the Neanderthals from Eurasia at some point bred with the homo sapiens of Africa.) Others believe that certain groups of men evolved in a completely different time period in a completely different place.
Human characteristics have evolved all throughout history and have been manipulated on a global scale through the use of science and technology. Genetic modification is one such process in which contemporary biotechnology techniques are employed to develop specific human characteristics. Despite this, there are a countless number of negative issues related with genetic modification including discrimination, ethical issues and corruption. Hence, genetic modification should not be used to enhance human characteristics.
My evidence for evolutions is how hippos have adapted to dominate by gaining helpful traits and evolving new ones. You’re probably thinking that hippos are a very dangerous and hurtful animal, which is true, but they are very important in their ecosystem and have evolved from many various animals to be the wonderful yet dangerous beasts they are today.
5.) Primates and all mammals share a series of characteristics such as: body hair, long gestation and live birth, mammary glands, different types of teeth, ability to maintain a constant body temperature, increased brain size and a considerable capacity for learning. Scientists created a special order called primates, because they share many characteristics unique to their order: a tendency toward erect posture, a flexible, generalized limb structure, hands and feet w/ a high degree of apprehensibility, retention of 5 digits on hands and feet, an opposable thumb, nails instead
There is great debate over the concept of primate evolution. Some research supports the idea that evolution occurred linearly as a continuum while other research supports the idea that fossils found to date should be separated into individual species. Through morphological, and geological evidence this paper explores this topic and provides concise arguments to further develop the understanding of human primate evolution.
When and why did Homo Sapiens begin to grow into a thriving population that have produced both cognitive and technological advances? No one knows for certain and because of this question countless amounts of people have decided to become anthropologists. Anthropology is defined as, “the study of human beings and their ancestors through time and space and in relation to physical character, environmental and social relations, and culture(Merriam-Webster). Despite all of the time and effort that anthropologists have put into discovering the correct response, the answer to this question is constantly changing because population, cognitivity and technology are constantly changing too. One way to determine how these factors affect Homo Sapiens is by studying past societies. The development of technology expanded rapidly in the Upper Paleolithic era. The technological and cognitive advances made by the growing Upper Paleolithic people changed their lives for the better and allowed them to adapt to their environment in innumerable ways.
“The scientific study of how humans developed did not begin until the 1800s in Europe. Until that time, people relied on religious explanations of how humans came into existence. Starting in the 1500s a scientific revolution began to sweep Europe. Thinkers started using scientific methods and experiments to try to better understand the world and the creatures living in it. Eventually these methods were turned to the question of human origins” (The Nature Of Human Origins, 1). Earth made it possible for species to change over time because Ancient Earth provides ability to plenty of time.The Homo Sapien a is very complex creature. The species started off very simple by living in caves and surviving with little food and then later evolved into a species that were able to do many more complex things. The first species was Sahelanthropus tchadensis They were one of the most simple humans in that time period and on. They had very small skulls compared to Homo Sapiens today and their motor skills were just the same. We have evolved and changed for the better both mentally and physically. The Evolution of Homo Sapiens started off simple, such as the Neanderthals, and now we are the most advanced species to ever walk the planet so far.
Are we still evolving? How do humans and apes share a common ancestor? Modern human species or Homo sapiens have shown great similarities in the physical and genetic makeup to another group primates species, the apes. Both organisms share a common ancestor dating back eight to six million years ago. Evolution means change over time. Human evolution is the process by which humans have emerged from apelike ancestors. Through sequences of mutations, genetic drift, migration, and natural selection and technology we are able to observe the amazing amount of similarities and diversity of humans to other living organisms. Humans have roamed the earth for about six million years. At least, that is from when the oldest human ancestor was discovered.
What evidence shows the changing from the early hominids to the modern humans? Throughout the human evolution body parts like legs and harms have changed for the better. By the early hominids being biped, meaning they are able to stand and even walk on two feet, it helped them to be able to do more things like getting around more and help with their tool making and hunting. A lot of the fossils discovered were found in the Great Rift Valley in East Africa, which contained many different lakes and small rivers. For many years researchers have been finding new species. These species have been named Australopithicus, robust australopithecines , Orrorin tugenensis, Homo habilis, Homo erectus, neanderthal, and Homo sapiens. These early hominids and modern humans really show off how the features and behaviors have really changed in time.
The evolution theory, one of the most significant theories, laid groundwork for the study of modern biological science. This theory has lead scientists into unending debates due to lack of empirical supports. Until the mid-eighteenth century, when Charles Darwin came up with an explanation to evolution, scientists, then, began to endorse this hypothesis. In “Natural Selection,” Darwin explains the natural selection, a plausible mechanism that causes evolution, to gain approval of his cynical audience for his evolution theory. He supports his claim with numerous examples of animals and plants that have developed traits beneficial for survival. A century later, Stephen Jay Gould, influenced by Darwin’s work, supports the evolution theory with a different method. In “Evolution as Fact and Theory,” Gould, in contrast to Darwin, criticizes his detractors, the creationists who believe that every life form is the creation of a supernatural being, to reinforce the validity of the evolution theory. Gould undermines creationism by emphasizing its misused concepts of theory and popular philosophy, proving that it is not science. Besides denouncing creationism, Gould also provides theoretical examples as evidence to prove evolution is a theory. Despite their different approaches, both Darwin and Gould effectively prove the existence of evolution.
Evolution is the complexity of processes by which living organisms established on earth and have been expanded and modified through theorized changes in form and function. Human evolution is the biological and cultural development of the species Homo sapiens sapiens, or human beings. Humans evolved from apes because of their similarities. This can be shown in the evidence that humans had a decrease in the size of the face and teeth that evolved. Early humans are classified in ten different types of families.
Human species or in scientific terms know as, Homo Sapiens has evolved drastically in the last couple of billion years. Human evolution all started from our great ancestors, the chimpanzees. Human evolution started all in the continent of Africa. Due to global changes, evolution changed over time. Thus leading to the evolution of mankind. But man didn't just evolve from chimpanzees. There were a lot of scientific processes and different events that led up to final evolution of mankind. But what does it mean humans evolved from chimpanzees? Why is the human evolution such a small speck in the evolution graph of the evolution of the whole earth? These questions that have been asked frequently by curious people has led scientists to dig deeper into this topic. The answers to how humans evolved has led to some great discoveries.
Natural selection is based on the concept “survival of the fittest” where the most favourable individual best suited in the environment survive and pass on their genes for the next generation. Those individual who are less suited to the environment will die.
